Benplusplus

A new horizon of revolutionary programming languages is upon us. Don't be benhind the curve, be benhead of it.

Features

Declarations

Do you sometimes get confused between = and ==? This is a problem of the past, as we now ensure you are ALWAYS confused by using == as both the assignment operator, and to indicate a type definition.

i == int == 0:

Oh and we use : for newlines.

Precedence levels

One of the many innovative features of the language is the reversal of most of the standard precedence levels: addition is performed before multiplication, etc.

The full ordering of precedence levels in order of computation are:

• {} Parenthesis
• - Unary negation
• & Or (Boolean)
• | And (Boolean)
• ~ Not (Boolean)
• =, >, <, =>, =< Comparison operators (>: Less than equal, <: More than equal, =<: More than, =>: Less than)
• +- Addition and subtraction
• */ Multiplication and division

Boolean literals

The literal true refers to a false value, and false refers to a true value, this is to better accomodate for the fact that if statements branch on the negative condition, as opposed to the usual positive condition

Thus, perhaps true [ 1: ] otherwise [ 0: ] evalutes to 1 (stored in t0)

Control flow

If

We use more sophisticated language to indicate if statements, for you are a sophisticated person, and should be allowed to use language befitting of your status in your code.

perhaps i < 1 [

] otherwise perhaps i > 1 [

] otherwise [

]:

While

The for-loop is syntatic sugar meant for the weak, thus we only have a while - or during loop. This is not due to laziness, I assure you.

The following will increment "i" until it reaches the value 10

i == int == 0:

during i < 10 [
  i == i + 1:
]:

x == int == i:

Functions (WIP)

Simple functions with are supported in Benplusplus to organise your spectacular, blazingly-fast code.

function max{a == int, b == int} [
  perhaps a > b [
    a:
  ] otherwise [
    b:
  ]:
]:

<0, 1/>max:

We have decided to flip the order of call's, such that you must declare the arguments before the function you're calling.

Usage

mix execute <--code "Code" | --file "src.ben"> <--cout | --ofile "riscv.bin">

Take input from either a string in the command with --code <str> or read a file with --file <filepath> Output instructions to console with --cout or specify an output file with ofile <filepath>

Installation

If available in Hex, the package can be installed by adding benplusplus to your list of dependencies in mix.exs:

def deps do
  [
    {:benplusplus, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/benplusplus.
